WebDec 19, 2024 · Moment of inertia. Moment of inertia is the name given to rotational inertia, the rotational analog of mass for linear motion. ... If an athlete wants to increase the speed of rotation, then they must decrease the radius by bringing the segments of the body closer to the axis of rotation thus decreasing the radius and moment of inertia. The moment of inertia about an axis of a body is calculated by summing for every particle in the body, where is the perpendicular distance to the specified axis.
